Product Description:

The MDD090A-N-030-N2M-110PA2 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. With motor size 090 and length code A, this unit is intended for digital drive controllers that require closed-loop speed and position control. By converting commanded current into tightly regulated torque, it serves pick-and-place axes, packaging stations, and other industrial automation equipment that depend on repeatable movement profiles. Its compact format also suits machine sections where accurate motion must be maintained during frequent starts, stops, and directional changes. It is also well suited to synchronized machine axes that must accelerate quickly and settle without excessive overshoot.

A centering diameter of 110 mm aligns the flange to adjacent mechanics, while all terminations exit on Side A through a single connector that helps keep cable routing orderly. The motor delivers a continuous standstill torque of 3.7 Nm, and its rated speed reaches 3000 rpm under the proper drive conditions. For vertical axes or controlled stopping functions, the blocking brake provides up to 11.0 Nm of holding torque. The motor uses a standard housing with standard rotor balancing, and the shaft is a single-ended keyed design without a side B extension. This arrangement supports straightforward installation when the motor is mounted in confined machine frames or near guarding panels.

Position data returns to the controller through Digital servo feedback (DSF) working with an integrated multiturn absolute encoder, so the drive can retain position information after power loss. Because the encoder stores absolute position across multiple revolutions, the control system can recover axis location more quickly after a power cycle. A fitted shaft seal helps keep coolant and dust from traveling along the shaft into internal areas. The machined keyway provides positive torque transfer to compatible hubs during reversing operation and repeated indexing cycles. The sealed shaft area also helps the motor remain suitable for machines where airborne dust or light fluid exposure is present.
